Article 187 of Mexico’s General Law of Commercial Companies reads: “La convocatoria para las Asambleas deberá contener la Orden del Día y será firmada por quien la haga” (The notice of a shareholders’ meeting must contain the agenda and be signed by whoever issues it).
Under Article 188, a resolution adopted in breach of these rules is void, unless all the shares were represented at the vote. Article 194 requires the minutes to be entered in the company’s minute book.
